okay i found out that when it is used as an adjective it is standard to drop the -s

Don't worry yourself OP,
90 degree angles don't exist since they don't reflect in all dimensions.

>>9784732
That should be "a 90-degree angle of attack".
Someone got lazy and didn't hyphen it.
Like a 20-year-old brainlet or a brainlet that's 20 years old.

"90-degree" is a compound adjective so it has no plural form. "of" is a preposition, "90" is a numeral and "degrees" is a plural noun.

>>9784732
>a 90-degree angle
"90-degree" is a compound adjective, so ir has no plural form.
>an angle of 90 degrees
"degrees" is a plural noun, with "of" and "90" being a preposition and a numeral respectively.

>a 90 degree angle

Degree is being used an adjective, which is why it's in singular form

>fuck the english language why
well said

>why is it plural in one case but not in the other
because the english language grew naturally and is full of idiosyncrasies and historical clutter.
>The problem with defending the purity of the English language is that English is about as pure as a cribhouse whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary.

and dont even get me started on their "phonetic" writing system

almost as bad as the chinese "one picture per word" shit

>>9784732
because 'degree' is being used as a unit in the first case and a quantity in the second case

There are so many wrong answers in this thread.

>>9784732
>>a 90 degree angle
>an angle of 90 degrees

It's plural when counting individual degrees and singular when you're referring to the angle as a unified object with a particular property.

>>9786136 is right.
English "grew". Most native-speakers know what "sounds" right even when they're unaware of the formal rules. English has many fewer strictures (and more exceptions) than other languages, languages which didn't "borrow" any words they found useful. (The French are particularly stuffy about trying to keep their language "pure".)

As a result, English is easier to learn than most other languages. Forget Nominative, Dative, Vocative, etc. But it's harder to pronounce.

You can often tell which side of the American Civil War a speaker's ancestors fought on by noting whether they refer to "THE United States" of "THESE United States".

In first example you have a single 90-degree, angle. In the second example you have 90 1-degree angles.
